srv_alloc (Extended Stored Procedure API)
This feature will be removed in a future version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible. Use CLR integration instead.
Allocates memory dynamically.
The srv_alloc function is equivalent to the Microsoft Windows API GlobalAlloc function. Normal Windows API C run-time memory management functions can be used in an Extended Stored Procedure API application.
You should thoroughly review the source code of extended stored procedures, and you should test the compiled DLLs before you install them on a production server. For information about security review and testing, see this Microsoft Web site.
